They were crack troops, skilled in the techniques of unconditional warfare, the soldiers of the special Forces - and the focus of Hollywood's first feature film about the Vietnam War: The Green Berets. John Wayne stars in and co-directs this red-white-and-blue depiction of America's Vietnam effort, based on Robin Moore's novel. Wayne wrote to President Lyndon Johnson to request military assistance for the film - and got more than enough firepower to create an impressive spectacle. Its soldiers fit the tried-and-true mould of earlier Wayne war classics like Back to Bataan and Sands of Iwo Jima. Their heroics are timeless.
